How to calculate the flange quote formula?
A formula for calculating flange quotations, but such formulas are widely spread over the network and vary from one to another, and the results are different. In fact, there is no constant formula for the price of the flange, but it depends on the specific process of production. So I decided to have a quotation about flange quotation and let you know how our manufacturers quote. In fact, there is nothing to keep secret.
According to the round steel process, the forging blank blanking, workshop workers. These three aspects of the impact, there is no point in the foundation is difficult, it is best to calculate the flange finished weight, price, and then calculated according to flange finished weight flange price.
Well, I come with you to analyze the existing problems of the calculation formula, this formula is not actually a few written, there are certain to me now to analysis:The first formula is as long as the steel industry in the people to see that, this algorithm is certainly a problem, the problem in 0.616, 10 mm per metre weighs 0.616 kg, and (diameter * outer diameter - diameter - * * * aperture aperture hole number) * actual volume = flange thickness. The latter 0.00001 CM is the calculation of the results into g. such a calculation method, I temporarily ignore how he results, first of all, there is a theoretical error, ask the volume of *0.616= weight?The theory cost and actual operation cost cost, the general foreign trade company own calculated price bargain with us, so the price is called the theory of price, and we are holding the actual cost of operation between manufacturers, often makes us uncomfortable is the theory cost and actual cost gap.Let's analyze some of the most widely used formulas for calculating flange weight on the web:(outer diameter * outer diameter * inner diameter * bore bore diameter * hole diameter * hole number * thickness *0.616*0.0001 unit cmExternal diameter * outer diameter * inner diameter * bore bore diameter * bore bore * thickness *7.93*0.0001 unit cmOutside diameter * outside diameter *1234*, thickness inner diameter * inner diameter *1234*, thickness *0.00001
